POST SEALING PART OF SEALED LEAD-ACID BATTERY

摘要

PURPOSE:To make the amount of an adhesive and the thickness of a battery constant and to increase the creeping resistance of electrolyte in a post by heat-bonding a frame and a film in the upper part of a post sealing part when the film and the frame are heat-bonded. CONSTITUTION:A film fixing part 3 installed in the form of wing in the upper part of a post sealing part is heat-bonded with a film when the circumference of a frame 2 is heat-bonded with the film 5. Since the volume of an adhesive pot 4 in the post sealing part can be made constant, the amount of an adhesive is made constant and the thickness of a battery is also made constant. Electrolyte creeping resistance in a post 1 is increased and the reliability of a battery is enhanced.
